Use AI to ATS-optimize your resume — skip Jobscan and Rezi

Status: Outline — full guide coming soon. Get notified when it ships →

What this covers

  • The 3-step AI prompt chain: extract JD keywords, audit resume, rewrite bullets
  • Why Jobscan / Rezi / Teal are doing exactly this under the hood — for ₹2K/month
  • The "verify the verbs are still yours" pass to keep the resume honest
  • A copy-paste prompt library you can use for any JD in 10 minutes

Why this matters for Indian devs going remote

Indian devs spend ₹15-30K/year on paid ATS tools (Jobscan, Rezi, Teal) that wrap the same Claude/GPT calls you can make yourself for free. That money is better spent on certs, conference tickets, or domain renewals. The AI prompt chain is also more controllable than the SaaS tools — you can audit the keyword list before applying it.

Outline

Step 1: Extract JD keywords with AI

TODO — the prompt that pulls 20-30 keywords from a JD, ranked by importance, with skill-vs-tool labels.

Step 2: Audit resume against keywords

TODO — the prompt that diffs resume vs keyword list and outputs missing terms with placement suggestions.

Step 3: Rewrite bullets

TODO — the prompt that rewrites bullets to include the missing keywords while preserving the original verb and number.

The honesty pass

TODO — the human review step: are the new verbs ones you can defend in interview? Cut anything you can't.

Common mistakes to avoid

  • Letting the AI write claims you can't back up in interview
  • Stuffing all 30 keywords without thinning the list
  • Not running the same prompt chain on each new JD (you'll fall back to generic)

Templates / examples

TODO — the full 3-prompt chain, a before/after resume example, and a "defensibility" review checklist.
